WATER-METER.

. Specification of Letters Patent.

Patented Aug. 2,1910.

Application filed March 18, 1910. Serial No. 550,256.

residing in he borough of Queens of the city of New York, in the State of New York, have inventedv certain new and useful Improvements in Water-Meters, 4of

which the following is a specification, reference being had to the accompanying drawing, forming a part hereof.

This invention relates to compound water meters in and which a high-duty metering device a low-duty metering device are combined,l a valve, operated by variations in the pressure differential, How through one of such meters,

acting to permit the and to prevent the flow through the other of such4 and it is particularly concerned with` the construction of the valve by which the flow through-one meter or the other is determined.

In accordance y with this invention a single valve body, located in a suitable valve chainber, is 'itself so chamberedor provided with channels and ports and so coperates with the channels or' branches ofthe conduit through which the liquid flows in its passage from the common inlet tothe common outlet through the as to control directly several metering devices,

the iow of the liquid through one or the other `of such metering devices.

The invention will b e more fully explained hereinafter with reference to the accompanying drawing which structur presents a view, partly in elevation and partly in vertical a compound meter section, which embodies the e represented in the relatively high-duty metering ively low-duty metering device 6, are preferably, although not necessarily, combined These metering devices,

any suitable character, being shown as of the well adapted to regi flows of ',liquid, whilel is of the nutating in a single structure. moreover, may be of the metering device a turbine type, which" is ster accurately large the metering device b" disk type, which is '-.vell

adapted to register accurately small flows of liquid. -The metering devices are respectively provided, as

usual, with registering mechanisms, as at a and b.

In the structure shown, there is a common inletor inflow opening for the l iquid at c and a comat the same time already described. cylindrical, as is preferable, a key o 1s prowhich enters at chamber e from which, accordin to t-he the inlet c passes into a position of the valve hereinafter re erred to, i

it iiows either through that branch of the common conduit which includes the highduty metering device a and thefchannel e', into the chamber f, whence it escapes through the outlet d, or through that branch which includes the channel g, the channel k and the low-duty metering device b, directly. into the channel e and the chamber f is a wall z' the channels g and la, and a valve chamber lc provided with a port Z which `opens into the common outlet chamber .fr The valve chainber is .preferably cylindrical and may be in which are formed provided with a lining sleeve m which has ports g', l1. and Z, corresponding respectively with the channels g and h and the port Z above mentioned. In the valve cham-v ber la is a valve body a which is freely movable vertically, its downward movement being limited by 4a flange n', which rests upon the sleeve or lining m and indirectlylupon the wall in 'which the valve chamber k is Aso j formed. The valve body n is chambered, as t at n2, so as to establish communication between the channels g and It when the valve body is in its lowest position, as shown in the drawing, the communication between these two channels being cut off when the valve bodyis lifted by the outflow.' The valve body is also .chambered from its lower end, as at n, in coinmunication with such chamber n3 having a port 11.*, which, when the valve body n is raised by-an increase in the pressure differential,v registers with the port Z 'direct communication with the chamber f preventing 'the iow o liquid through the .channels g and li as If the valve body n is vided to prevent rotation of the valve body in its chamber.

The operation of the valve will be readily understood in view of the foregoing description of the construction and of the functions of the several features. When the flow of liquid is relatively small and the pressure differential between the inlet and the outlet is relatively small and insufficient to raise the branch or channel e',

and places the branch e in` an increase in thev pressure differential between the infiow and the valve bodyl n, the flow of liquidlthrough the high-duty meter a will be prevented and the flow of liquid through `the low duty l meter Zr will be permitted, while if the pressure differential increases suiciently to lift the valve body n, the'iow of liquid through vthe low-duty meter b will be prevented and the flow through the high-duty meter. a; will,`

be permitted.'l It willbe observed thatin the embodiment of the invention shown m the drawing, the flow. of liquid through thehighl duty meter is prevented by shutting off the branch' in which it is located between the meter and the outlet, while the'iow of liquid .through the loivdutymeter. is prevented by shutting off the branch between the inlet and the low-duty meter, this relative arrangement being desirable for manufacturing reasons although not essential.

I claim as' my invention: lrsThe combination of a relatively highduty meter, a relatively-low-duty meter, a.

common conduit having branches in which the two meters are respectively located, the,

iniow'and the loutflowbeing common to both branches, a single valve chamber having lateral and end openings communicating with both branches and with the common outflow,

a valve body' located in said Valve chamber and chambered to permit ovg when in one position through one branch and to prevent iow throng ne' other: branch and, in the A .other positiy to prevent flow through the -first mentioned branch and topermit flow through the last mentioned branclh' 2. The combination of a relatively high-l duty meter, a relatively low-'duty `meter, a common 'conduit having branches in which the two meters are `respectively located, the

iniowand the outflow being common to40 both branches, a wall located between the branch which includes the high-duty .meter l between said channels when in one position and.` to establish communication between the channel of-.the high-duty meter'and the outflow whenjin another position. l

vThis specification slgned and witnessed I this 11th day of. March, 1910.
